Patent SE-0701681-L (SE)
Inventor: OTTERTUN HARALD
Filed: 2007-07-11
Abstract: An etching and recovery method is described, wherein articles made of copper are etched with an acid aqueous solution of etching chemicals containing Cu2+ for oxidizing Cu0 to Cu+, chloride ions, oxidizing agent which oxidizes Cu+ to Cu2+, and pH-adjusting hydrochloric acid. The technical problem to be solved is to make it possible to circulate the etching solution between the etching process and the recovery process during the recovery of used etching solution in such a manner that a closed circuit can be maintained between the processes. This is effected in that a regenerated etching solution containing a lower quantity of Cu2+ than the used etching solution is produced and in that the recovery process has an extraction step in which removed etching solution is mixed with an organic extraction solution of a complexing compound with which Cu2+ forms a copper complex which can be extracted in the organic extraction solution, after which the two mixed liquids are separated once again in order to obtain an organic extraction solution containing said copper complex, and regenerated etching solution. The method is carried out with an etching solution having a pH above 1.5 and a high copper content.

Abstract: The positions of target reflectors at a distance from a measuring station are measured with fan-shaped angularly sweeping beams of radiation emitted from the measuring station and reflected back to a detector there when each beam is intercepted by a reflector. Expected reflector distribution is analyzed to ascertain, as between adjacent reflectors at equal distances from the station, the minimum projected distance expectable between such reflectors in a separation direction in which separation can be maximum and the maximum projected distance between them in the transverse direction. Each of at least two beams has its long cross-section dimension oriented to be at an angle to that of the other and at an angle to the separation direction which is such that its tangent value is greater than the ratio of said maximum distance to said minimum distance. Each of those beams is swept to move between intersection with an origin point on one side of a solid angle space swept by the beams and intersection with another point that is on the opposite side of said space and is spaced in the separation direction from the origin point. Angular positions of both beams are assigned increasing magnitudes with increasing distance from the origin point, for unambiguous measurement of target positions. For a given orientation of long cross-section dimensions of each beam, targets at like distances from the station must each be in an hour-glass-shaped region of isolation related to that beam orientation.

Abstract: A support structure for unitizing coil turns into a single member and bracing each coil of a multi-coil stator dynamoelectric machine. Each stator coil includes several turns relatively concentrically disposed. Each coil turn constitutes two longitudinal conductor portions and two end turn conductor portions. One end turn portion serially connects two longitudinal portions and the remaining end turn portion serially connects one of the longitudinal portions with a longitudinal portion of a concentrically adjacent coil. Each coil preferably lies in a plane defined by a portion of a cylinder and the coils are disposed in a cylindrical arrangement having a longitudinal axis therethrough such that one longitudinal portion of the outermost coil turn lies along the outer radial extent of the cylindrical arrangement and the remaining longitudinal portion of the outermost coil turn lies radially nearer the longitudinal axis of the cylindrical arrangement. A rigid foundation member is situated in the plane of each coil within the concentrically innermost turn. Turns of each coil are structurally connected either directly to the foundation member or indirectly to the foundation member by being intermediately joined to a turn already joined to the foundation member. The concentric turns of each coil are separated by a predetermined distance through the use of interposed spacer members situated at desired axial and circumferential locations. Such coils present a spiral pancake appearance and are cooperatively disposed in the cylindrical arrangement between radially inner and outer supporting structures. Appropriately shaped wedges are disposed between selected coils and internal/external supporting members to account for the skewed or spiral manner in which each of the coils is arranged in the substantially cylindrical arrangement. Radial tie rods extending between the radially internal and external support members structurally integrate those members so as to insure structural integrity of the cylindrical arrangement. The radially external support member is preferably configured to extract load components from individual coil turns exposed at the cylindrical arrangement's outer periphery by either having radially inwardly directed struts extending between adjacent turns or having notches within which the radially outer conductor turns, when canted, are receivable.

Abstract: In the formation of engagement grooves in the shank of a tool for use in a hammer drill or chipping hammer, a matrix or die is divided along a junction plane into two matrix halves. A bore for holding the tool to be punched is formed along the junction plane so that the plane divides the bore in half in its axial direction. Guide openings are formed in the opposite sides of the matrix extending into the bore for receiving punching dies. The matrix halves combine to form these guide openings which are located in the junction plane so that the punching pressure is applied in this plane. The closing pressure for holding the matrix halves together is applied at right angles to the junction plane.
